TextItem example 7
How to set text spacing and aspect ratio
This example can be created using HLU C library calls, HLU FORTRAN library calls, or NCL. This example demonstrates how to set the text spacing and aspect ratio of a string. The names of the source files for this example are tx07c.c, tx07f.f, and tx07n.ncl.
Discussion
This module discusses how to create this plot using HLU function calls
or NCL. A resource file is not used with this example. A detailed discussion of how this example works appears in its source code.
Creating the plot using HLU C library calls
The HLU C program that generates this plot is called tx07c.c.
Creating the plot using HLU FORTRAN library calls
The HLU FORTRAN program that generates this plot is called tx07f.f.
Creating the plot using NCL
The NCL script that generates this plot is called tx07n.ncl.
The data
This plot does not use any external data.
